Using Magento 2.2.4 - I have the Auth.net Direct Post payment method enabled, the Magento Auth.net patch applied, and with the configuration:
Transaction Details Url:
I'm seeing the transactions in the Auth.net sandbox
(TESTMODE) This transaction has been approved
but an error is being thrown on the Magento side:
Please enter a transaction ID to authorize this payment
I've tried with Test Mode both enabled and disabled. How can I get this working properly?
